1918. Serial No. 240,980. I 7

To all whom it may conce fin:

Be it known that I, ALFRED G. F. KUROW- sin, a citizen of the United States, formerly a citizen of Germany, residing in Brooklyn borough, in the county of Kings, city and State of New York, have invented certain new and useful Improvements in Typewriting Machines, of which the following is a specification.

My invention relates to typewriting machines, and is herein disclosed as applied to tally-strip devices on an Underwood stand ard typewriter. Such devices are usually used for preserving a tally-strip record of items on sales sheets, bills, etc, and usually include a holder both for the tally-strip itself and for the carbon paper which makes the duplicate record thereon of the original I on the bill or sales sheet. Such devices therefore are advantageously constructed, so as to feed the tally-strip along at each operation of the line-space mechanism; but for the purpose of making a condensed record, the feeding of the tally-strip is advantageously th minimum line-space, whereas the linespacing of the original work-sheet is often considerably larger, to enable the bill or sales sheet to present an agreeable appearance.

This present invention relates specifically to mechanism including a plurality of rolls for supporting the tally-strip and carbon paper holding device above referred to, and

to subordinate parts and auxiliary features of the tally-strip supporting device, this present invention being divided out of my copending application, Serial No. 154,650, filed March 14, 1917 (now Patent No. 1,302,- 676. dated May 6, 1919). v

The object of my invention is to provide an improved mechanism including a plurality of rolls for supporting the tally-strip and the carbon-strip used in conjunction therewith, all as will hereinafter and at length appear.

My invention is illustrated in its preferred embodiment in the drawings accompanying and forming a part of this specification, although it will be appreciated that the same may be embodied in other forms, not illustrated, and that my invention includes all such variations and modifications of the particular tally-strip supporting mechanism illustrated, and hereinafter described and claimed, as come within the scope of the coneluding claims wherein the particular features in which my invention consists are pointed out. i

Other features and advantages will herelnafter appear.

In the accompanying drawings,

Figure 1 is a perspective view showing my invention as applied to the carriage of an Underwood typewriting machine.

Figure 2 is a sectional view showing a clamp for catching the leading end of the tally-strip and securing it to the roll upon which it is wound.

Figure 3 is a fragmentary View also illustrating the holding mechanism shown in Figure 2.

Figure 4 is a sectional view showing the roll-supporting device upon a plane extending longitudinally of the typewriter platen, and upon a larger scale than it is shown in Figure 1.

Figure 5 is a perspective view showing the means for fastening the mandrel or spindle ofthe tally-strip roll in place.

. Figure 6 is an end view of the fastening means shown in Figure 5.,

Figure 7 is a fragmentary View showing a detail of the carbon-paper-roll support.

In the usual Underwood typewriter carriage the platen 1 is fast upon a supporting shaft which is ournaled in the end plates 3, 1 of the platen frame of the typewriter carriage, which shaft is provided at its ends with knobs, one of which is shown at 5,

whereby it may be rotated.

The typewriter carriage includes the usual auxiliary features for holding the paper in place upon the platen, and for advancing the platen, the latter mechanism including a line-spacing lever 15 through which the line spacing mechanism is operated to advance the platen, as will be appreciated.

,At the right-hand end of the carriage is located a tally-strip device which includes a pointed spindle 24, on which is mounted a roll of paper 25 adapted to be used as a tally-strip. The free end this paper is carried down across the paper table 13 beneath the platen and up in front of the platen until its leading edge reaches a winding roll 26, said'roll comprising a spring 27 under ported from the end plates 3, 4,. thus allow.-

ing the section 28 to turn freely upon said shaft, motion being transmittedthereto by the tally-strip web 25 acting as a belt and the section 28 serving as an abutment or support for the tally-strip at the point at which the type-bars of the machine engage the same.

' In order to drivethe tally-strip as the line-spacing mechanism is operated, the roll 26 is adapted to be driven from and by the line-spacing mechanism, said roll for this purpose being fast upon a shaft 29, which is journaled in the ends of the side pieces 30 and 31 of the roll-supporting frame. Adjacent the outer end of the shaft 29, there is secured fast thereto a ratchet wheel 32, which ratchet wheel is adapted to be engaged by a pawl 33 to thereby advance the shaft 29 and wind the tally and carbon sheets thereon. The pawl 33 is operated from the line-spacing mechanism at the left-hand end -or the carriage, motion being transmitted to said pawl through a long rock-shaft 34 supported in bearings carried by the carriage. The mechanism, however, through which motion is transmitted from the line spacing mechanism to the pawl 33 and ratchet wheel 32 is not illustrated in detail in this present application, as the same is in no way involved herein. Such mechanism is, however, illustrated. and described at length in my patent, above referred to.

The mandrel or spindle 24, on which the paper or tally-strip roll 25 is carried, is adapted to be thrust in through the wall 31 of the tally-strip device through the center of the roll 25, and is long enough to extend beyond the wall 30, in which position it thrusts aside a latch or catch 74 in the form of a slide. This catch (Figures 4, 5 and 6) has two sides 75 and 76 cut out at 77, so that where cut out at 77, the mandrel 24 may enter between the two sides 75 and 76. The slide 74 has a turned-over end 78 by which s; adapted to be pressed down against the tension of a spring ,70, which normally holds the catch 74 in its upper position. The catch 74 is guided by its two sides 75 and 76 in a hood 80 having tenons 82, which engage and align within slots cut in the wall 30, said tenons also carrying a.

.bushing 83, which extends within and beby its spring 70. The knurled right-hand extension 85 of the mandrel 24 is large enough to prevent the mandrel from slipping too far when inserted into the opening 86 in the wall 31 in which it is journale'd.

In order to make it impossible for the tally-strip paper roll 25 to be wrongly placed on the nandrel 24, said roll 25 has a spool or core 87, which extends entirely out to one end 88 of the tally-strip or paper roll while cut away and terminating short of the opposite end thereof. I/Vhen the'roll is to be inserted in the tally-strip device, an end plate 89, having a bushing 90 extending inwardly therefrom and adapted to complete the core for the roll 25, is inserted in the roll, and then the roll is inserted between the walls 30 and 31, with its end 88, together with the adjacent end of the core 87, bearing against a spider spring projection 91 which is adapted to hold the roll tightly when the roll is inserted so that the core orroller 87 bears against the margin of the opening in the spider. When thus inserted, the end of the bushing 90 bears against the adjacent end of the core 87 and a hub in the form of a boss 93 on the end plate 89 bears against the wall'31. The mandrel passes through the end plate 89, the core 87, the opening in thespider 91, and out until it enga es andis caught by the catch 74. The spider 91 has its outlying spring ends bent S-shaped to catch in openings in an end plate 94 which has a hub in the form of a boss 95, said hub adapted to engage the boss-bushing 83 and to be fastened thereto by a set screw 96.

The winding roll 26 may include a wooden body 97, which is held by a set screw 98 to its shaft 29. Said shaftis journaled in the end walls 30 and 31, and to hold it in position, it is provided with a shoulder 99 bearing against the inside of the end wall 30, and it is also provided with a collar 100 outside the end wall and lying closely against said wall, said collar being held to the shaft 29 by a set screw 101. In order to provide friction to prevent the winding roll 26 from turning too easily, a spider friction spring 102 bears against the inside of the wall 30, and the outlying arms thereof bear against the flange 103 of said winding roll 26.

In order to make it easy to catch the end of a tally-strip on said winding roll, the spring catch. 27 lies in an axial slot 104 on said roll, and said spring is hinged at the opposite side of said roll at 105 (Figures 2 and 3), with the result that the arc-shaped portions of the spring extending around to the hinge point furnish sufficient springiness to hold the main part of the spring in its slot 104, to thereby clamp the leading edge of the tally-strip. In order to make it easy to raise the sping catch, a finger-hole 107 is cut out of the winding roll. The carbon paperused with these tally-strips is often in the form of a single rolled strip or web having two colors. In order'to make sure that the typist shall insert this rolled strip or carbon-web roll 107 correctly on its pointed mandrel or spindle shaft 108, it is provided with a spool or core which extends entirely out to the left-hand side 110 thereof, and also entirely out to the right-hand side 111. This core or roller, in the illustrated em-. bodiment of the invention, comprises wooden end plugs 109 connected together by an outer shell 109 which may be of metal. The right-hand end plug 109 is axially recessed or apertured to receive the inwardly-extending hub or bushing 111 of a flange plate 112, and for this urpose, the wooden core end 109 at the right is provided in its outer end with two end recesses or openings 113, either one of which may engage a pin 114 which projects endwardly inward from the face of the flange 112 for the purpose of entering one or the other of the holes 113, thus compelling the flange to revolve with the roll 107 and its core.

Said flange plate 112 is provided with an outwardly-extending hub or boss 115 which bears against the plate 31 and which also forms the support for a detent 116 which is adapted to lock the flange plate 112 to the mandrel 108, so that the two revolve together. The detent 116 (Figures 4 and 7) is seated in a bore 117 and is pressed inwardly by a spring 118, so that when in the proper position, said detent is adapted to enter into a longitudinal slot kerf 119 in the mandrel 108, and when thus seated, the mandrel and the flange turn as a unit. The spring 118 encircles the hub 115 and is held in place by a pin 120, which extends across a cutaway segment of the hub 115.

The outer end of the mandrel 108 has suitably attached thereto a crank handle 121, for the re-winding of a carbon-roll, and by which it may revolve and the adjustments are such that when a carbon roll is in position on the mandrel 108, the turning of the handle 121 will cause the detent 116 to seat itself so that the carbon roll will turn with the handle. r

The end 110 of the carbon roll, together with the left-hand end plug 109, bears against a spider spring 122-, which may be substantially like the spring 91, and bears against a flange plate 123, which is mounted like the plate 94 on a hub 124, and held by a set screw 125 to the internal extension of a hub or bushing 126. This hub includes a latch 127 like the latch 74 and the other parts may be substantially identical so that the mandrel 108 may be released from the latch 127 which normally holds it by depressing the upper end of the latch. When the carbon-web roll 107 is inserted its end 111, the adjacent end of the shell 109 and the recessed outer end of the right-hand core plug 109 all bear against the flange plate 112.

l/Vhile the paper roll 25 and the carbon roll turn freely on their shaft or mandrel, the winding roll 26 is fast to the shaft by the set screw 98. v

The inner hub or bushing 111 for the carbon-web roll 107 is not adapted to be received by the tally-strip paper roll 25 having the core 87, by reason of the fact that the bushing 111 projects too far; and the bushing 90 for the tally-strip roll 25 is not adapted to be received by the right-hand core plug 109 of the carbon-web roll 107*, by reason of being of too small a diameter. Also, in the construction shown in the drawings, the projecting pin 114 would prevent the spool end or flange plate 112 from being applied to the tally-strip roll 25.

The frame which comprises the side pieces 30 and 31 supporting the roll 26, etc., is adapted to be swung either into a nearly upright position, which is the normal position shown in full lines in Figure 1, or thrown down either forward or backward into nearly horizontal positions. This enables the rolls to be swung down when the machine is not in use, thus reducing the height of the machine and enabling it to fit in an ordinary cover, or to occupy an ordinary typewriter desk, into the body of which it may slide when the cover of said desk is pulled into horizontal position. In order to permit this, the side pieces 30 and 31. are journaled on the shaft 29, which shaft in turn is journaled in brackets 159.

The brackets 159 are formed as turned-up extensions of a plate 160 which extends be tween them, thus giving rigidity to the structure. Fast to the right-hand bracket 159 is an extension collar 161, on which the side piece 31 is journaled instead of directly on the shaft 29. This collar 161 is circular except at a point near the bottom but slightly in front of the bottom, at which point a hollow 162 (Figure 4) is cut into it, which hollow is adapted to fit a-detent roller 163, said roller being journaled very loosely in openings 164, formed in the downward extension 165 of the side wall 31 and also in the upturned extension 166 of said wall, which is spaced therefrom and lies against the end of the collar 161. The roller 163 is pressed strongly against the collar 161 by a broad flat spring 167, which throws the roller 163 into the hollow 162, when the roll frame is in the proper operating position. The frame, however, may be swung from said position by pressure of the hand, thus forcing the roller 163 to ride out of its hollow and ride on the circular face of the collar 161.

Variations may be resorted to within the scope of the invention, and portions of the improvements may be used Without others.
